Abstract
Electronically focused and automatically scanning acoustic bulk waves are produced by scattering chirp acoustic bulk waves at grazing incidence from an acoustic grating. The same apparatus may be used in reverse to convert diverging acoustic bulk waves produced by a focused beam into chirp acoustic bulk waves. A pulse compression filter then converts the chirp waves into signals describing the source.
